Bingo. As frustrating as it might be, the more I think about it the more I know this is a very good thing. It's tempting to want Life to Be Fair. Going by the rote scoring system might ensure fairness, but it doesn't guarantee a good fit.
Each medical student cohort is
136 people. Honestly, I can't even personally imagine what that could be like... my graduating class from HS was >900 people. 136 people is an extended family. The admissions committee that doesn't consider how all of our personalities are going to mesh or clash is doing us all a disservice.
What if your spouse were assigned to you by a computer, based on some arbitrary scores and input? If we can't choose our own new family, then the least we can wish for is that a (hopefully insightful) matchmaker will try to arrange us into a harmonious group. If that means I'm left out because They think I would be horribly incompatible with this class cohort, well, y'know, maybe they know something I don't.
They can't control the final spree of withdrawals and waitlist movements, but they can and do reserve the right to load the dice before the final roll.
Good Night, and Good Luck.
